After "apt-get"ing tuxracer which required me for some
reason to also install the latest version of gcc, g++, libc6
and libstdc++2.10, I could no longer compile anything. All
the builds that I tried failed at the linker stage with
missing symbols. Wishing for a backout option in apt-get, I
thought I tried upgrading some other key library and
development packages. I finally got the system back into a
working state when I upgraded binutils which contains the
gnu linker.
